used in examinations by positron emission tomography (PET). The medicine FLT (F) Synektik is administered before the examination.
After administering a small amount of FLT (F) Synektik, the doctor will take pictures with a special device
(tomograph), on the basis of which they will assess the patient's condition and progress in treating the disease.
The doctor will administer the medicine only if the clinical benefits of using the radiopharmaceutical product
